DCM Sistemes ALS2315A Diffuse Ringlight

Optically you size this light by working distance and aperture. DCM rates a recommended working distance of 80-400 mm, a wide window that suits both close benchtop stations and taller fixtures. The 145 mm inner diameter sets a practical floor on the field of view it can cover cleanly without the ring itself vignetting the image, so it is matched to medium-to-large parts rather than tiny components a small ringlight would handle. Wavelength is selectable at order time: 470 nm blue (the configured variant here), plus 525 nm green, 630 nm red, 850 nm IR, white and RGB. Shorter wavelengths like the 470 nm blue scatter more and give crisper edges on fine features, red and IR penetrate and can cut through certain colourations or print, and white is the general-purpose choice; pick the colour to maximise contrast against the specific defect or mark you need to read.

Electrically and from an integration standpoint the ALS2315A is designed to drop in without a separate lighting cabinet. It runs on 24 VDC (+/-3%) through a 2-pin male chassis connector (PIN1 +24 V, PIN2 0 V), and DCM's inline iBlueDrive driver is built into the light, so no external controller is required for basic operation; a 3-pin aerial connector exposes the iBlueDrive control. It supports both continuous (Type C) and strobe operation (Type S / iBlueDrive Type i), letting you run it always-on for steady inspection or pulse it in sync with the camera trigger to freeze motion and boost peak intensity on fast lines. Continuous draw is 17 W for the 470 nm, 525 nm and white variants and up to 21 W for the 850 nm IR. The housing is aluminium for heat dissipation, the unit weighs 880 g and is only 13 mm thick, and protection is IP40 (rising to IP43 when mounted so light falls vertically), placing it in clean-to-moderate factory environments rather than washdown zones.
